[Opensim-users] Still trying to set up groups - progress and problems

Tue Oct 25 15:24:33 UTC 2011

I got groups mostly working with the XoopenSim module located at:
http://www.nsl.tuis.ac.jp/xoops/modules/xpwiki/?XoopenSim so there are some
obvious differences in our configuration, but I remember having a weird
issue when I tried to install the module that was related to using MySQL
5.x. and I also had a problem with the Profiles module that I never did
solve, with a very similar error to what you're seeing:

15:54:17 - [PROFILE]: Unable to connect to Profile Server
http://fleepgrid.com/grid/modules/xoopensim/helper/profile.php. Method
avatar_properties_request, para
ms System.Collections.Hashtable. Exception System.Xml.XmlException: Data at
the root level is invalid. Line 1, position 1.
15:54:17 - [LLCLIENTVIEW]: Caught exception while processing

15:55:26 - [XMLRPC-GROUPS-CONNECTOR]: An error has occured while attempting
to access the XmlRpcGroups server method groups.getGroupMembers at
http://fleepgrid.com/grid/modules/xoopensim/helper/xmlgroups.php
15:55:26 - [XMLRPC-GROUPS-CONNECTOR]: The underlying connection was closed:
An unexpected error occurred on a receive. at
System.Net.HttpWebRequest.GetResponse()

I think I ended up commenting out the Profile parts and haven't gotten back
to it yet, so interested in hearing any others' results.

In case it's helpful, my full change log and install notes are at
http://fleep.wikispaces.com/FleepGrid - have to scroll down to the 9/17/11
entry for the notes on the groups and profiles modules..

Sorry I can't be of more help - I haven't figured it out myself yet!

Sincerely,

- Chris/Fleep
